Observation System & Site(s):
  1. Anemometers and Wind vane: Wind sensors are installed respectively on the center part of the runways, and near the two ends of the touch down zones, for measuring wind direction and wind speed. They are about 10M above the runway surface. Information from these wind sensors is sent to the control towers, meteorological offices and flight information stations. Readout displays include the instantaneous wind direction and wind speed, 2-minute and 10-minute average wind direction and wind speed, and 10-minute wind peaks.
  1. Runway Visual Range (RVR): The sensors, synchronized with visibility, are installed on the center part of the runways, and near the two ends of the touch down zones, for measuring RVR between the cockpits (5M) and the runways for an average height 2.5M above the ground. RVR is measured and reported whenever the horizontal surface visibility is less than 1500M, and the RVR is given after the VIS of METAR code.
  1. Ceilometer: They are installed near to runway touch down zones, for measuring the cloud heights over the final approach areas.
  1. The temperature and Dew point sensor: They are installed near the "Anemometers and Wind vane" and are used for measuring the air temperature and dew point near the height of aircraft engines. The sensors are usually located at the height of 1.5±0.3M above runway surfaces.
  1. Doppler Weather Radar: Installed at Taipei/Taiwan Taoyuan Int'l Airport.
  1. LLWAS system: Installed at Taipei/Taiwan Taoyuan Int'l Airport and Taipei/Songshan Airport. The detection area is between runway level and 500M (1600FT) above that level along the runway and extends 3NM from both thresholds. (Detection area of RWY 28 at Taipei/Songshan Airport extends 2NM from THR 28). Advisories concerning wind shear/microburst will be provided by ATC, judging by the situations of air traffic and the situations of alert.
    Types of alert:
    1. Wind shear alert: 15 to 29 knots wind speed losses, or greater than 15 knots wind speed gains.
    2. Microburst alert: 30 knots or higher wind speed loss.
 

3.5.4 TYPES OF SERVICES

  1. Pre-flight operational planning
    Weather information, including the 24-hour FL300, FL340 and FL390 prognostic charts, the 24-hour en-route significant weather prognostic chart and terminal forecasts, is given to the pilot-in-command or operator's representative for each flight by notifying the Taipei/Taiwan Taoyuan International Airport, Kaohsiung International Airport, Taipei/Songshan Airport  Flight Information Station as earlier as possible. Whenever possible, the pilot-in-command is given a verbal briefing by a flight information specialist face to face, or this service may be carried out by telephone from an appropriate meteorological office.
  1. In-flight operational planning
    Landing or take-off weather conditions and trend-type forecasts are provided in METAR form available throughout 24 hours of the day. Aerodrome warnings, for the purpose of protecting parked aircraft, are available at the airport Flight Information Station.
 

3.5.5 NOTIFICATION REQUIRED FROM OPERATORS

The operator's local representative, or the pilot-in-command should notify the airport Flight Information Station of the purpose to obtain weather service normally H24 before the estimated time of departure and whenever any flights are advanced, delayed or cancelled, or extra requirements are needed, requests should be made as earlier as possible.
 

3.5.6 AIREP

Pursuant to Annex 3, Chapter 5, when air-ground data link is used and automatic dependent surveillance (ADS) is being applied, automated routine observations should be provided every 15 minutes. Special observations shall be made by all aircraft whenever the following conditions are encountered or observed:
  1. moderate or severe turbulence; or
  2. moderate or severe icing; or
  3. severe mountain wave; or
  4. thunderstorms, without hail, that are obscured, embedded, widespread or in squall lines; or
  5. thunderstorms, with hail, that are obscured, embedded, widespread or in squall lines; or
  6. heavy dust storm or heavy sandstorm; or
  7. volcanic ash cloud; or
  8. pre-eruption volcanic activity or a volcanic eruption.

  1. General
    For the safety of air traffic, TAMC (Taipei Aeronautical Meteorological Center) maintain a continuous watch over meteorological conditions affecting flight operations within the lower and upper Taipei FIR and when necessary, SIGMET and AIRMET information is issued by TAMC. Furthermore, aerodrome warnings are issued to operators, in accordance with local arrangements, by all aeronautical MET offices at aerodromes.
  1. Meteorological watch
    The meteorological watch is performed by TAMC. The TAMC issues SIGMET and AIRMET information in accordance with Annex 3, Chapter 7.
    The TAMC is responsible for issuing information in the form of SIGMET message about the occurrence and/ or expected occurrence of the following significant meteorological phenomena:
    1. Thunderstorm
    2. Tropical cyclone (Typhoon)
    3. Cumulonimbus
